摘要
本文分别在品质性状、经济性状和质量性状上对浙江省70份白菜型油菜地方品种间进行相关系数的测算,揭示了品种间在这些性状上的亲疏关系和遗传距离,并用动态模糊聚类的方法将70份品种分为三类。结果显示;(1)原产地为浙北和宁绍平原的地方品种基本上属于一类,而丘陵山区的品种分属其余两类;(2)一般同县份的地方品种亲缘关系较近。
The 70 local rape varieties(B.campestris)in Zhejiang were carried out calculation for correlation coefficients,on characters of qualitative and quantitative respectively.It revealed relationships among characters and genetic distances in varieties.These varieties used a method of fuzzy cluster analysis were classed into 3 groups Most of varieties in flatlands of Zhejiang northern and Ning-shao were gathered into same group,while those from hill areas into the other two groups.It showed that these varieties originated from same county likely have a close genetic relationships.The result of this study offers an aid to utilize these local varietyresources resonablly.
